RAZOR.

Specification of Letters Patent.

Patented Feb. 10, 1914.

Application iled January 29, 1913. Serial No. 744,975.

To all whom it may concern:

lie it known that I, HOWARD OsnoRNn Micinun., a citizen of the United States ,of America, residing at the city of Baltimore, State of Maryland, have invented certain new and useful Improvements in Razors, of which the following is a specification.

'ihis invention relates to safety razors and particularly to a new and improved blade and guard or holder, and means for attaching the blade to the guard.

Various means have been devised for mounting safety razor blades or attaching them to the guard, but these different devices are imperfect in their operation for various reasons. ln some instances the clamping means by which the blade is held on the guard projects on the blade side of the instrument so that the razor cannot be held at a sufficiently acute angle with the face, with the result that the razor operates with a scraping rather than a cutting action. In other instances the nature of the clamp is such that the blade is not firmly held or is diflicult to attach or detach, and many of the clamps in use are of such a nature that they greatly increase the cost of producing the razor.

The device of the present invention is so constructed that is does not protrude on the blade side of the razor, that is, it is not presented to the face in shaving so that the side of the blade toward the face is flat and there is nothing other than the will of the operator to determine the angle at which the blade shall be held in shaving. Thus the most eicient and comfortable position of the razor can be adopted. Also the device is simple and positive in its operation in that it holds the blade rigidly in position. It is also so simple in construction that it can be applied to the razor at a very slight cost, so that by the use of the invention safety razors can be produced with increased economy, thereby making it possible to reduce the price of the product.

In the preferred form of the invention the guard is provided with one or more apertures preferably placed centrally of its transverse dimension, and the blade is provided with corresponding projecting members forming one or more loops or arches corresponding in number and position to the apertures in the guard to be passed through the guard when the blade is in position, and

a wedge or pin is provided to be placed on the opposite side of the guard from the blade and passed through the loops where they project from the guard.

Preferably the guard is provided with two or more apertures, and the projecting members on the blade, which are to cooperate with the apertures, are formed by punching holes in the blade, one to correspondto each openingr in the guard, the material thus punched out of the blade 'being turned up to form the loops referred to, but, as shown, these loops are broken centrally to afford increased facility in ha ndling the material, and each loop, in fact, consists of two tongues, one on each side of each aperture formed in the blade. The pin, as shown, is in the form of a double wedge. though it may have as many wedges as there are openings in the guard and loops on the blade. The wedges are formed in alinement and are connected by a reduced portion of the pin. With the device thus constructed, to remove the blade, it is not necessary to completely withdraw the wedge. It need only be withdrawn until the reduced portion instead of the wedge is within the loops, when it may be removed directly at right angles to the surface of the blade, the reduced portion of the wedge passing through the opening between the tongues forming the loops.

The accompanying drawings illustrate a safety razor to which the device of the invention in its preferred form has been applied.

Figure `1 is a plan of the razor with the guard, the blade and the blade holder in operative position thereon. Fig. 2 is a side elevation of the guard with the blade attached. Fig. 3 is a transverse cross-section taken on the line 3, 3 of Fig. l. Fig. 4 is a perspective view of the blade, and Fig. 5 is a perspective viev7 of the wedge.

Referring to the drawings by numerals, the guard which is indicated by reference character l is apertured at 2, see Figs. 1 and 3, at a plurality of points, and the blade 3 is provided with corresponding loops or apertured projecting members 4 adapted to be passed through the openings 2 when the blade is placed on the guard in operative position in registration therewith, as shown in Figs. 1, 2 and 3. Preferably the projections lon the blade 3 are formed, as has been stated, by punching openings 5 therein,

see Fig. 4, the material displaced being severed centrally and turned up to form the projections or loops.

With the blade in position on the guard, as shown in Figs. 1, 2 and 3, it is locked in position by means of the pin 6. see Fig. 5, which is thrust through the openings 7 in the. projecting members 4, the enlarged wedge portions 8 and 9 on the pin 6 being forced into the apertures 7 j to produce the desired locking or clamping effect, the Wedges being formed with a dimension corresponding to that of the aperture 7 to produce this result. To the same end the Wedge 6 is formed with a reduced portion 10 intermediately of its length, and when it is desired to unlock the blade, the Wedge need only be Withdrawn until the reduced portion 10 is Within the aperture 7 of one'of the projecting members 4. Then the wedge may be Withdrawn in a direction at right angles to the blade by passing the reduced portion 10 through the opening 11 between the members forming the projections 4. It will thus be apparent that the device referred to is simple to construct and operate, and, further, that While it gives a positive and convenient clamping action, it is so formed and placed that it does not interfere with the shaving operation and can be produced at an extremely low cost.

I have thus described specifically a single embodiment of my invention in order that its nature and operation may be clearly understood. However, t-he s citic terms herein are used in their descriptive rather than in their limiting sense and the scope of the invention is defined in the claims.

I claim- 1. In a safet razor having a blade and a guard, means or fastening the blade to the guard, consisting of an apertured projecting member on the dat side of the blade, the guard being correspondingly apertured so that the projection on the blade may be thrust through thevguard and a pin carrying a wedge member placed on the opposite side of the guard from the blade and passed through the aperture in the projection on the blade.

2. In a safety razor having a blade and a guard, means for fastening the blade to the guard consisting of a plurality of apertured projecting members on the flat side of the blade, the guard being correspondingly apertured so that when the blade is placed in registration With the guard, the projecting members thereon pass through the guard, and a pin having a plurality of Wedge members corresponding to the project-ions on the blade placed on the opposite side of the guard from the blade and forced through the apertures in the projecting members, each Wedge occupying the corresponding aperture.

3. In a safety razor, a blade formed with punched apertures, the material displaced from each aperture forming an apertured projecting member, a guard apertured .to receive the projecting members so that these projecting members extend through the guard, and a pin placed on the side of the guard opposite the blade and thrust through the apertures in the projecting members to hold the blade in position on the guard.

4. In a safety razor, a blade and a guard, the blade being punched to form an aperture, the displaced material one member on each side of the aperture converging to form a projecting member which is apertured in the direction of the plane of the blade, the guard being correspondingly apertured to receive the projection so that the projection extends through the guard, and a Wedge placed on the opposite side of the guard from the blade and thrust into the aperture in the projecting member thus formed.

5. In a safety razor, a guard, a blade having material punched out of the intermediate portion thereof forming an aperture, the displaced material on each side of 'the aperture converging to form a projecting member, but the ends of the displaced portions being spaced apart slight-ly so that the projecting member is open at its end, a guard correspondingly apertured to receive the projecting member, and a pin having a Wedge portion to it snugly into the aperture of the projecting member beyond the guard, and a reduced portion adapted to pass through the aperture between the ends of the displaced portions of the blade material when the pin is partially Withdrawn.
